To research the formation and the strength of the explosive fly-materials (EFMs)generated by the linear shaped charge (LSC),an experimental method was put forward.Firstly,based on some discov-ery in the cutting experiment on LSC,the necessity and essentiality of the research were demonstrated. Secondly,a series of experiments to collect and investigate EFM were conducted.It is found that EFM is mainly formed as lamellar or spherical metal particles.And the harmful effects caused by EFM are mainly related with the charge and the shell material of LSC.Finally,by analyzing the harmful effects,a new method for EFM research and a momentum formula of EFM was established.
